3 MODERN REVOLUTION – LAST HALF OF 20 TH CENTURY 1. Process sedimentology and modern facies models : Fisk (Mississippi fluvial models), API 51 Gulf Coast (directed by Francis Sheppard) oil company facies models – Shell (Rufe Leblanc and Beau Bernard), Brazos River point bar, Galveston barrier bar; Exxon, (Harold Gould) cheniers; Arnold Bouma, turbidities. Bob Ginsburg and Shell carbonate group at Coral Gables 2. Plate Tectonics , Tuzo Wilson, late 1960s, led to genetic classification of basins 3. Concept of depositional systems introduced, W. L. Fisher and J.H. McGowen (1967): “3D assemblage of lithofacies genetically linked by active (modern) process or inferred (ancient) process and events” integration of modern facies models of process sedimentology to the sequence and spatial concepts of Walther; first Gulf Coast, then Paleozoics
